Tax Analysis

The estimated annual property tax is $16,228 across all districts. With a homestead exemption claimed, that drops to $14,811 — saving $1,417 per year. That's $1,234 per month a buyer should budget. The assessed value increased roughly in line with the neighborhood, so a tax protest is unlikely to yield significant savings.
